School Infrastructure and Support Mechanisms include the knowledge, resources, and organizational structures necessary to operationalize and implement all of the components of MTSS in a unified system to meet the identified implementation and outcome. This collection of resources summarizes the infrastructure and support mechanisms outlined in Section 5 of the MTSS Fidelity of Implementation Rubric as necessary for successful MTSS implementation. The infrastructure elements are summarized in the Do You Have the Right Infrastructure for MTSS? infographic.

Sustained Implementation of MTSS is dependent on building the capacity of the organization to lead and support the essential MTSS components. This is done by leadership teams who share the responsibility to support all adults in the school building by planning, coordinating, monitoring, and adjusting MTSS implementation activities.

Leadership teams are responsible for building the capacity of the team to lead the work as well as providing ongoing training and support to staff, families, and community partners to implement as intended. Leadership teams should have broad representation and an established process to regularly solicit input and collect data from staff, students, families, and community partners. This feedback helps drive implementation decisions. These teams also use validated tools to assess capacity, and Schoolwide PBIS Tiered Fidelity Inventory and Reading Tiered Fidelity Inventory to assess fidelity of implementation in order to prevent drift from the core, evidence-based features of the system.
